Multiple Toolbars (Firefox 1.5.0.7)

Over time I have added multiple toolbars to my Firefox browser. Several of them have lots of blank space. Is there a way to get two toolbars such as Sticky and Purple Bunny to co-exist on the same line?

Or minimize them to an icon so I could call them when needed, instead of always taking space away from the browser window?

The only toolbar I have, Web Developer Extension's toolbar, spans the full width of the window. It does not appear to be designed to share the row with another one. I'm not sure whether this is by the designer's choice (and I simply have to accept it) or whether it is a user-configurable feature.

Thanks to those who responded! I have solved my problem and greatly increased my screen space with yet another Firefox extension: MenuX.
( https://addons.mozilla.org/firefox/786/). Now I have 9.75" out of 10-5/8" of vertical screen space available, ~92% of possible, with tabbed browsing. Used to be 53% with tabbed browsing and all toolbars visible. And I can easily show any toolbar I need with one mouse click.

Caution: For Firefox up to v1.5.0.7. Developer Website indicates a v2.0-capable extension due out in November. A fix to the current download is shown in user comments, but I have not tried it yet.
